Wouldn't it be better to rework the support for u-boot tools in general? (I know, this will be tricky, since U-Boot environment tools compilation is really an adventure). Also I think, we should use the same version of U-Boot tools as we use for the U-Boot itself. What do you think? For reference here is an internal used version of the u-boot-tools Makefile (known to work with U-Boot versions from our BSP for TQMa53 / TQMa6x). Should work at least for U-Boot 2013.01 and 2013.04 You need to provide a target specific /etc/fw_env.config 8<-------------------------------------------------------------------- # -*-makefile-*- # # Copyright (C) 2012 by Andreas Bießmann <andr...@biessmann.de> # # See CREDITS for details about who has contributed to this project. # # For further information about the PTXdist project and license conditions # see the README file. # # # We provide this package # PACKAGES-$(PTXCONF_U_BOOT_TOOLS) += u-boot-tools # # Paths and names # U_BOOT_TOOLS_VERSION := $(U_BOOT_VERSION) U_BOOT_TOOLS_MD5 := $(U_BOOT_MD5) U_BOOT_TOOLS := u-boot-$(U_BOOT_TOOLS_VERSION) U_BOOT_TOOLS_SUFFIX := tar.bz2 U_BOOT_TOOLS_URL := http://ftp.denx.de/pub/u-boot/$(U_BOOT_TOOLS).$(U_BOOT_TOOLS_SUFFIX) U_BOOT_TOOLS_SOURCE := $(SRCDIR)/$(U_BOOT_TOOLS).$(U_BOOT_TOOLS_SUFFIX) U_BOOT_TOOLS_DIR := $(BUILDDIR)/$(U_BOOT_TOOLS) U_BOOT_TOOLS_LICENSE := GPLv2 $(STATEDIR)/u-boot-tools.extract: $(STATEDIR)/u-boot.extract @$(call targetinfo) @$(call touch) $(STATEDIR)/u-boot-tools.prepare: $(STATEDIR)/u-boot.prepare @$(call targetinfo) @$(call touch) # ---------------------------------------------------------------------------- # Prepare # ---------------------------------------------------------------------------- U_BOOT_TOOLS_PATH := $(U_BOOT_PATH) # U_BOOT_TOOLS_MAKE_OPT := $(U_BOOT_MAKE_OPT) tools U_BOOT_TOOLS_CONF_TOOL := NO U_BOOT_TOOLS_MAKE_OPT := \ HOSTCC="$(BOOTLOADER_CROSS_COMPILE)gcc" \ HOSTSTRIP="$(BOOTLOADER_CROSS_COMPILE)strip" \ CROSS_COMPILE=$(BOOTLOADER_CROSS_COMPILE) \ tools # HOSTCC="$(CROSS_CC)" \ # HOSTSTRIP="$(CROSS_STRIP)" \ # tools ifdef PTXCONF_U_BOOT_TOOLS_TOOL_ENV U_BOOT_TOOLS_MAKE_OPT += env endif # ---------------------------------------------------------------------------- # Install # ---------------------------------------------------------------------------- $(STATEDIR)/u-boot-tools.install: @$(call targetinfo) install -D $(U_BOOT_TOOLS_DIR)/tools/env/fw_printenv \ $(U_BOOT_TOOLS_PKGDIR)/usr/sbin/fw_printenv @$(call touch) # ---------------------------------------------------------------------------- # Target-Install # ---------------------------------------------------------------------------- $(STATEDIR)/u-boot-tools.targetinstall: @$(call targetinfo) @$(call install_init, u-boot-tools) @$(call install_fixup, u-boot-tools,PRIORITY,optional) @$(call install_fixup, u-boot-tools,SECTION,base) @$(call install_fixup, u-boot-tools,AUTHOR,\ "Andreas Bießmann <andr...@biessmann.de>") @$(call install_fixup, u-boot-tools,DESCRIPTION,missing) ifdef PTXCONF_U_BOOT_TOOLS_TOOL_ENV @$(call install_copy, u-boot-tools, 0, 0, 0755, -, /usr/sbin/fw_printenv) @$(call install_link, u-boot-tools, fw_printenv, /usr/sbin/fw_setenv) @$(call install_alternative, u-boot-tools, 0, 0, 0644, /etc/fw_env.config) endif @$(call install_finish, u-boot-tools) @$(call touch) $(STATEDIR)/u-boot-tools.clean: @$(call targetinfo) -rm $(STATEDIR)/u-boot-tools.* # @$(call clean_pkg, U_BOOT_TOOLS) # vim: syntax=make 8<-------------------------------------------------------------------- Regards Markus -- ptxdist mailing list ptxdist@pengutronix.de
